1.1 Important information:
ATTENTION!
The device is not suitable for operation with a frequency converter.
ATTENTION!
Use the heat pump controller included in the scope of supply to operate
the air-to-water heat pump.
ATTENTION!
When transporting the heat pump, care must be taken to ensure that it is
not tilted more than 45° (in any direction).
ATTENTION!
The heat pump and transport pallet are only joined by the packing film.
ATTENTION!
Do not restrict or block up the area around the air inlet or outlet.
ATTENTION!
Only operate the heat pump with the air ducts connected.
ATTENTION!
Never use cleaning agents containing sand, soda, acid or chloride
because these could damage surfaces.
ATTENTION!
We recommend the installation of a suitable corrosion protection system
to prevent the formation of deposits (e.g. rust) in the condenser of the
heat pump.
ATTENTION!
Before opening the device, ensure that all circuits are isolated from the
power supply.
ATTENTION!
Any work on the heat pump may only be performed by authorised and
qualified after-sales service technicians.
1.2 Legal Regulations and
Directives
The construction and design of the heat pump complies with all
relevant EU directives, DIN/VDE regulations (see CE declaration
of conformity).
When connecting the heat pump to the power supply, the rele-
vant VDE, EN and IEC standards are to be fulfilled. Any further
connection requirements stipulated by local utility companies
must also be observed.
When connecting the heating system, all applicable regulations
must also be adhered to.
1.3 Energy-Efficient Use of the
Heat Pump
With the purchase of this heat pump you are helping to protect
the environment. A prerequisite for energy-efficient operation is
the correct design of the heat source system and heating system
(radiators and circulation pump).
It is particularly important for the efficiency of a heat pump to
keep the temperature difference between heating water and heat
source as small as possible. For this reason, it is advisable to de-
sign the heat source and heating system very carefully. A tem-
perature difference of approx. one Kelvin increases the
power consumption by around 2.5 %. When designing the
heating system, it should be borne in mind that special consum-
ers such as e.g. hot water preparation should also be considered
and dimensioned for low temperatures. Underfloor heating
systems (panel heating) are optimally suited for heat pump use
on account of the low flow temperatures (30 °C to
40 °C).
It is important to ensure that the heat exchangers are not con-
taminated during operation because this increases the tempera-
ture difference, in turn reducing the COP.
Correct adjustment of the heat pump controller is also important
for energy-efficient use of the heat pump. Further information can
be found in the heat pump controller's operating instructions.
